Fuel cartridge interchangeability

1 Scope
This International Standard covers interchangeability of micro fuel cell (MFC) fuel cartridges
to provide the cartridge compatibility for a variety of MFC power units while maintaining the
safety and performance of MFC power systems. For this purpose, the standard covers fuel
cartridges and their connector designs. Fuel type, fuel concentration and fuel quality are also
covered. This standard also provides for the means to avoid the miss-connection of an
improper fuel cartridge. Test methods for verifying the compliance with the interchangeability
requirements for fuel and fuel cartridges are also provided in this standard.
IEC/PAS 62282-6-1 and IEC 62282-6-200 do not cover fuel cartridge or fuel from the cartridge.
IEC 62282-6-300 describes the performance test methods of fuel cartridges, the fuel from the
cartridge, and markings to realize the interchangeability of fuel cartridges. These include
performance effect of fuel cartridges, such as fuel quality which may affect the performance of
MFC power units and usable fuel volume from fuel cartridges.
A MFC power system block diagram is shown in Figure 1. MFC power systems and MFC
power units are defined as those wearable or easily carried by hand, providing d.c. outputs
that do not exceed 60 V d.c. and power outputs that do not exceed 240 VA. This standard
covers the fuel cartridge for MFC power units and the mechanical interface of connectors
between fuel cartridges and MFC power units. The main body of this standard includes
methanol liquid fuel cartridges, including methanol and water solution. Annex A shows the
background used to determine the forces expected in normal operation and in foreseeable
misuse. Annex B shows the example design for test fixtures for the fuel connector and fuel
cartridge type tests.
NOTE Liquid fuel means fuel transported from a cartridge to a MFC power unit in the liquid state, and gas fuel
means fuel transported from a cartridge to a power unit in the gaseous state.

4.1 Basic requirements
4.1.1 Safety
Fuel connectors shall comply with the safety requirements in Subclause 4.10.3, Fuel valves,
Subclause 4.17, Fuel supply construction, and pass type tests described in Clause 7 in
IEC/PAS 62282-6-1.
4.1.2 No leakage and no fuel vapour loss
4.1.2.1 No leakage and no fuel vapour loss shall occur at fuel connectors in the process of
connecting, using and removing of cartridge. Requirements listed under 4.1.2.2 through
4.1.2.5 shall be applied to all fuel cartridge types.
4.1.2.2 The cartridge side connector shall have an orientation feature(s) and/or mechanical
feature(s) to ensure that the cartridge can only be connected in the proper orientation and
that a wrong cartridge is prevented from being connected to the MFC power unit. These
features ensure that the following conditions are met.
a) Improper connection of the cartridge by the user to the MFC power unit shall not damage
the cartridge side connector or MFC power unit side connector in any way that will result
in leakage or fuel vapour loss when they are subsequently connected together properly,
when the cartridge is subsequently connected properly to another MFC power unit, or
when the MFC power unit is subsequently connected properly to another fuel cartridge.
b) Attempting to connect the cartridge to a wrong MFC power unit shall not damage the
cartridge side connector or MFC power unit side connector in any way that will result in
leakage or fuel vapour loss when a correct cartridge is subsequently connected properly to
the MFC power unit or when the cartridge is subsequently connected properly to a correct
MFC unit.
c) Attempting to connect the cartridge to the MFC power unit with a force expected in normal
operation or foreseeable misuse shall not result in leakage or fuel vapour loss, or
otherwise result in subsequent leakage or fuel vapour loss if used properly in the future.

4.1.2.3 If a force expected in normal operation or foreseeable misuse is applied to the
cartridge and/or MFC power unit while the cartridge is connected to the MFC power unit, there
shall be no leakage and no fuel vapour loss under the following conditions.
a) If a cartridge is connected to a MFC power unit and loading is applied to the cartridge or
MFC power unit, there shall be no leakage and no fuel vapour loss.
b) If the cartridge can be connected to the MFC power unit after unintentional loading, there
shall be no leakage and no fuel vapour loss. If another cartridge cannot be connected to
the MFC power unit, there shall be no leakage and no fuel vapour loss.
4.1.2.4 If a force expected in normal operation or foreseeable misuse is applied to the
cartridge side connector and/or MFC power unit side connector while the cartridge is being
removed from the MFC power unit, there shall be no leakage and no fuel vapour loss under
the following conditions.
a) Attempting to remove the cartridge from the MFC power unit with a force expected in
normal use shall not result in leakage or fuel vapour loss or otherwise result in
subsequent leakage or fuel vapour loss if used properly in the future.
b) Improper removal of the cartridge by the user from the MFC power unit shall not damage
the cartridge side connector or MFC power unit side connector such that: when another
cartridge is connected properly to the MFC power unit or when another MFC power unit is
connected properly to the cartridge, there shall be no leakage and no fuel vapour loss. If
the cartridge cannot be removed from the MFC power unit, there shall be no leakage and
no fuel vapour loss.
4.1.2.5 If the cartridge side connector is damaged while the cartridge is being connected,
used or removed by a force expected in foreseeable misuse, the following requirements shall
be met.
a) Leakage or fuel vapour loss shall not be detected even if the cartridge side fuel connector
is damaged.
b) When the cartridge side connector is damaged at its coupling part, no leakage and no fuel
vapour loss shall be caused if the MFC power unit side connector is connected, used, or
removed. This is not intended to include any damage to the MFC power unit caused by a
user with an obviously damaged cartridge.
c) If the cartridge side connector is damaged, it shall be easy for the user to remove the
damaged cartridge and/or any broken parts of the cartridge from the MFC power unit side
connector. The connection of a new cartridge to the MFC power unit shall not be affected.
d) The MFC power unit side connector shall not be damaged. The cartridge side connector
shall be designed with suitable connector material so as to cause the MFC power unit side
connector no damage.
